Question

0.86332495807108 in nearest tenth

Answer 1

Rounding...
1. If a number ends in 1, 2, 3 or 4, then round down.
2. If a number ends in 5, 6, 7, 8 or 9, then round up.

t = the place of the number
tenths = 0.t
hundredths =0.0t
thousands = 0.00t
and so on.

0.863324...
0.8 is the tenth place and you will need to look at the number directly to the right of the number which is 6. Since it is 6 you will round 0.8 to 0.9. Understandable?
